Task 1
A first attempt at producing a html webpage to advertise a phone recycling company is shown below.
Wanted! Your old mobile phone for cash! Click to visit www.phonerecycle.co.uk Here at PhoneRecycle we can pay you for your old working mobile phones. We recycle the components and refurbish handsets ready for their next use. Please visit our website for a quote today!
The webpage was then improved using various html tags to provide the formatting shown below.

Task 2
A diving competition calculates the final mark for each dive based on the marks of six judges. Each judge awards a mark individually (up to a maximum mark of 6.0).
The highest mark and the lowest mark are recorded but not used to calculate the final mark. The final mark is calculated by adding the four remaining marks together and dividing by four.
Using a basic text editor, write an algorithm, which inputs six judges’ marks and outputs the lowest mark, the highest mark and the final mark. Save your completed algorithm as DivingAlgorithm.txt
For example, with inputs:
5.9 6.0 5.9 5.7 5.6 5.7
The output would be:
Highest: 6.0 Lowest: 5.6
Final Mark:
5.8

(f) Add a sound which will play every time a crab “eats” a wombat.
(g) Add a counter and edit the crab’s code so that the counter displays how many wombats the crab has “eaten”.
(h) Save your completed world as FinalWJECCrabs
